b04a43c87c Differentiate between AT45DB011 compatible large serial flash parts
and the AT24C08 small serial flash parts.  We still report these as
the same part (since we group things already), but now we recognize
the small serial versions as well.

ae06c30e2b Add a comment that says it looks like lucent cards have a primary
firmware revision as well (not sure which firmware versions are needed
for this, but the 6.x and 8.x 'software' versions that I have seem to
support it).

Add dBm comm quality RID.  This is like the normal comm quality rid,
except the signal and noise numbers are normalized to dBm.  Some
revisions of the prism firmware, however, don't support this RID, and
some that do support it return 0 for quality and/or noise.  Your
milage may vary.

a4be7ce2dd Add a macro for SLIST traversal 'SLIST_FOREACH_PREVPTR',
this macro keeps a pointer to the previous element's next
pointer to allow for search and O(1) removal.

c939f1aee7 Extend the interface to ether_input(): a NULL eh pointer means that
the mbuf contains the ethernet header (eh) as well, which ether_input()
will strip off as needed.

This permits the removal (in a backward compatible way) of the
header removal code which right now is replicated in all drivers,
sometimes in an inconsistent way. Also, because many functions
called after ether_input() require the eh in the mbuf, eventually
we can propagate the interface and handle outdated drivers just
in ether_input().

Individual driver changes to use the new interface will follow as
we have a chance to touch them.

NOTE THAT THIS CHANGE IS FULLY BACKWARD COMPATIBLE AND DOES NOT BREAK
BINARY COMPATIBILITY FOR DRIVERS.

2b5989e943 Fix handling of Receiver Not Ready errors when doing polling.
Also take this chance to cleanup the code in fxp_intr_body.

Add a missing block of code to disable interrupts when
reinitializing the interface while doing polling (the RELENG_4
version was correct).

fc1c73c21a Temporarily disable polling when no processes are active, while I
investigate the problem described below.

I am seeing some strange livelock on recent -current sources with
a slow box under heavy load, which disappears with this change.
This might suggest some kind of problem (either insufficient locking,
or mishandling of priorities) in the poll_idle thread.

e6e370a7fe - Replace v_flag with v_iflag and v_vflag
- v_vflag is protected by the vnode lock and is used when synchronization
   with VOP calls is needed.
 - v_iflag is protected by interlock and is used for dealing with vnode
   management issues.  These flags include X/O LOCK, FREE, DOOMED, etc.
 - All accesses to v_iflag and v_vflag have either been locked or marked with
   mp_fixme's.
 - Many ASSERT_VOP_LOCKED calls have been added where the locking was not
   clear.
 - Many functions in vfs_subr.c were restructured to provide for stronger
   locking.

8f1586dd65 Take advantage of the fact that there is a small 1MB direct mapped region
on x86 in between KERNBASE and the kernel load address.  pmap_mapdev()

1af04fadd1 Take a shot at fixing a nasty bug in the pmap changes that I did. I
missed the pmap_kenter/kremove in this file, which leads to read()/write()
of /dev/mem using stale TLB entries. (gah!)  Fortunately, mmap of /dev/mem
wasn't affected, so it wasn't as bad as it could have been.  This throws
some light on the 'X server affects stability' thread....

073eef8ca2 Add code that will download firmware to a Symbol LA4100-series of CF
cards.  Since the firmware is hard coded into the kernel, I've made it
a kernel option (WI_SYMBOL_FIRMWARE).

Note: This only downloads into the RAM of these cards.  It doesn't
download into FLASH, and is somewhat limited.  There needs to be a
better way to deal, but this works for now.  My Symbol LA4132 CF card
works now.

f2b17113cf Make the consumers of the linker_load_file() function use
linker_load_module() instead.

This fixes a bug where the kernel was unable to properly locate and
load a kernel module in vfs_mount() (and probably in the netgraph
code as well since it was using the same function).  This is because
the linker_load_file() does not properly search the module path.
